pkdsm2shadow

program to calculate sun shadow based on digital surface model and sun angles

SYNOPSIS

Usage: pkdsm2shadow -i input.txt -o output [-sza angle] [-saa angle]

Options: [-f value] [-ot type] [-of GDALformat] [-ct filename] [-co option]*

Advanced options: [–scale value] [–offset value]

Description

Utility to create a binary shadow mask from a digital surface model, based on Sun zenith (-sza) and azimuth angles (-saa).

Options

• use either -short or --long options (both --long=value and --long value are supported)
• short option -h shows basic options only, long option --help shows all options

  short	long	type	default	description
  i	input	std::string		input image file
  o	output	std::string		Output image file
  sza	sza	double		Sun zenith angle.
  saa	saa	double		Sun azimuth angle (N=0 E=90 S=180 W=270).
  f	flag	int	0	Flag to put in image if pixel shadow
  s	scale	double		scale used for input dsm: height=scale*input+offset
  off	offset	double		offset used for input dsm: height=scale*input+offset
  co	co	std::string		Creation option for output file. Multiple options can be specified.
  ot	otype	std::string		Data type for output image ({Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/CInt16/CInt32/CFloat32/CFloat64}). Empty string: inherit type from input image
  of	oformat	std::string	GTiff	Output image format (see also gdal_translate).
  ct	ct	std::string		color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid)

  Usage: pkdsm2shadow -i input.txt -o output [-sza angle] [-saa angle]
